Bird Evolution and Adaptations

Beginning with Archaeopteryx, this video looks at the emergence and adaptations of birds. Feathers from modified reptilian scales and hollow bones allowed flight, and this footage also looks at feather pigments. Other bird characteristics are also observed, including eggs, nests, offspring precocity, and migration.
